Seasonal Variation of Cistus ladanifer L. Diterpenes
The exudate of Cistus ladanifer L. consists mainly of two families of secondary metabolites: flavonoids and diterpenes. The amount of flavonoids present in the leaves has a marked seasonal variation, being maximum in summer and minimum in winter. In the present study, we demonstrate that the amount of diterpenes varies seasonally, but with a different pattern: maximum concentration in winter an...
متن کاملIntra-Population Variation of Secondary Metabolites in Cistus ladanifer L.
In previous studies, secondary metabolites in the leaf exudate of Cistus ladanifer, specifically aglycone flavonoids and diterpenes, were demonstrated to play an ecophysiological role. They protect against ultraviolet radiation, have antiherbivore activity, and are allelopathic agents. Their synthesis in the plant was also found to vary quantitatively and qualitatively in response to various en...
متن کاملIdentification of metalliferous ecotypes of Cistus ladanifer L. using RAPD markers.
The genetic diversity of Cistus ladanifer ssp. ladanifer (Cistaceae) growing on ultramafic and non-ultramafic (basic and schists) soils in the NE of Portugal was studied in order to identify molecular markers that could distinguish the metal-tolerant ecotypes of this species. Random Amplified Polymorphic DNA (RAPD) markers were used in order to estimate genetic variation and differences between...
متن کاملReutilización de datos lingísticos para la creación de un sistema de traducción automática para un nuevo par de lenguas
This work examines various ways to re-use pre-existing linguistic data to quickly generate a machine translation system for a new language pair. In particular, a machine translation system between Portuguese and Catalan based on the Apertium platform (www.apertium.org) has been built from data existing in this platform for translating between Portuguese and Spanish and between Spanish and Catal...
